OPERATING DEVICE FOR WASHING-MACHIN ES.

Application filed January 27, 1916.

To all whom t may concern.'

Be it known that I, LoUIs E. DIETZ, a citizen of the United States,residing at the city of Cincinnati, in the county of Hamilton and Stateof Ohio, have invented certain new and useful Improvements in OperatingDevices for IVashing-Machines, of which the following is aspecification.

My invention relates more particularly to the operating mechanism ofwashing machines and especially to that class known as the doublereciprocating rubber type.

Modern washing' machines must operate at high speed and 'produce amaximum amount of power through the use of a minimum amount of exertionor operating force, and they must also operate uniformly, smoothly7 andeasily, with little friction of the operating parts.

The object of my present invention is to combine elements and partswhich make up the operating mechanism, in a unique, simple and efficientcombination which will involve these objects and desired results iny thehighest degree, thereby evolving an ideal Washing machine of the typementioned.

In the accompanying drawing, forming part of this specification:

Figure 1, is a side View of the invention,

Fig. 2, is a sectional view on line 2 2 o1' Fig. 3,

Fig. 3, is a plan view of the invention, and

Fig. 4, is an end view thereof.

My invention as illustrated in the drawings, is mounted upon a doublerubber type of washing machine 1, in which I mount an oscillatingclothes receptacle 2, and a dasher 3, which are adapted to reciprocatesimultaneously in opposite directions to rub clothing between them. Onthe body 1l, of the machine, I hinge at 5, a lid 6 having an elongatedslot 7. The clothes receptacle 2 is pivotally mounted in the body 4, andis preferably detachably connected thereto and to the operatingmechanism. The dasher-3 is pivotally and slidably mountedV in detachablebearings in the lid or cover 6 and is carried thereby, so that when thelid is open, the dasher is withdrawn from its position within theclothes receptacle, to permit free access thereto.

Upon the hinged end of the lid 6, I rigidly secure a bracket 8, havingsupports 9 in which is mounted a gear shaft 10 which carries at itsouter end a pinion gear 12 and a Specificatonof Letters Patent.

fly wheel 13, which fly wheel gives increased momentum in the operationof the machine.

In brackets 14, I mount another gear shaft 15, which carries the largegear 16, and in brackets 17 I mount the oscillating shaft 18, whichcarries at its outer end, a downwardly extending arm 19, and to this armI pivotally attach one end of a link 20, which at its ing rod 241 whichpasses through the slot 7 and at its lower end is connected to thedasher 3. On the arm 22, I provide a short extension 25 to which ispivoted the upper end of a pitman 26, the other end whereof is connectedto J@he clothes receptacle 2.

To the side of the lid 6, at point 27, I pivotally connect a handle 28,to which I piv` otally connect one end of the connecting bar 21 and thenpivotally connect thel other end of said bar 21 to the large gear 16, atpoint 29. The dasher 8 and clothes carrying re` ceptacle'2, are eachprovided with clothes rubbing surfaces of any desired form.

When it is desired to operate the machine, the lid is opened and theclothes to be washed placed in the machine; the lid is then closed andsecured and the handle 28 operated back and forth. By operating thehandle 28 back and forth, the connecting rod is pushed forward andbackward revolving gear 16 to which it is connected, forcing a mesh withgear 12, thus imparting motion to the shaft 10 and consequentlyrevolving the Hy wheel 13; this operation of the handle also forces theconnecting bar 21 to impart movement and motion to link 20 which in turnoperates arm 19 and said arm being on oscillating shaft 18 oscillatesthe same, and this motion also oscillates the arm 22 and its extension25, thus arm 22 operates the pitman 23 forward and backward and throughthis action of said pitman a reciprocating motion is given to the dasher3 by agency ofl05 provide a cheap,

is attached and said arm oscillating with the shaft 18, a simultaneousbut oppositely reciprocating motion and action is given to the dasherand clothes carrying receptacle, causing them to produce the properrubbing and agitating effect upon the clothing to be washed, which havebeen placed in said clothes receptacle and beneath the dasher or rubber.

It will be understood that the oscillating shaft 18 and its extendingarms are continu-v ously operating and oscillating thusthe continuousrubbing of the clothes is progressing as the dasher and clothescarryingreceptacle are simultaneously reciprocating, but in oppositedirections.

By placing a belt over the fly wheel 13, power may be applied to operatethe machine and in this case, the upper end of handle 28 is dispensedwith.

I do not limit myselfl to the specific form of clothes cleaning oragitating mechanism in the tub, but may change.

It will readily become apparent that I simple and highly efficientoperating mechanism for washing machines which produces a maximum speedand power at minimum exerting force, and which `is durable and fixed,insuring uniformity of action and operation.

While I have described one specific form of applying my invention, it isobvious that the same mal be somewhat modified without departure fromthe spirit and principle of the invention and I wish to be understood asclaiming that such modifications will still fall Within the scope of myinvention.

What I claim as new and my invention and desire to secure by LettersPatent is t 1. In operating mechanism of the class de- Copies of thispatent may be obtained for five cents each, y'ny addressing the scribed,a dasher rod and a pitman, an oscillating shaft and outer and inner armsthereon, intermediate connections between the inner arm on theoscillating shaft and the dasher rod and pitman, a large gear and a flywheel, a small gear, a shaft, the small gear and fly Wheel both mountedon said shaft, said large gear meshing with the small gear so as torevolve the shaft and fly Wheel, a handle lever, a connecting rodbetween the large gear Wheel and handle lev'er and a link between thehandle lever and the outer arm, the operation of the handle leverimparting motion to the parts to operate the fly wheel and oscillate theoscillating shaft and connections so as to reciprocate the dasher rodand pitman. y

2. In operating mechanism of the class described, a dasher rod and apitman, a shaft, a pinion, a fly wheel, both mounted on said shaft, alarge gear wheel and a shaft for carrying the same, an oscillating shafthaving inner extensions and an outer extension thereon,said innerextensions connected to the dasher rod and pitman, a handle lever, aconnecting rod extending from the handle lever tothe large gear wheel, alink extending from the connecting rod to the outer extension on theoscillating shaft, the movement of the handle lever imparting motion tothe parts to operate the flyv wheel and oscillate the oscillating shaftand connections to reciprocate the dasher rod and pitman.
